Hello!

I’ve been having quite strange problem with Firefox for a few months since version 80.X on clean Windows 10 (reinstalled from scratch after secure erase; the latest 20H2 version with all updates installed). It’s worth to mention that I’ve been using Firefox like 15 years and never had an issue like this before.

Firefox just fills up system drive completely (50+GB to 0 bytes remaining) few times a day under active usage. It happens randomly and I can’t identify the reason. I also can’t find any actual files saved on disk because it seems to be related to NTFS cache. I’ve tried disabling the following settings with no success:

browser.cache.disk.enable cached-web-content_cached-web-content browser.cache.memory.enable browser.cache.disk.smart_size.enabled

And couldn’t find any solution unfortunately. I usually have 2 windows opened ("common" and private) with 10 to 30 tabs each which is not much at all for i7/16GB I believe. This problem is extremely annoying and seriously affects SSD life so I'd really appreciate if someone would help me to resolve it. Thanks in advance!

Why is Firefox 78 writing to disk constantly? Even when the browser is idle, the hard drive light on my computer blinks non-stop, and I can hear the constant noise coming from the hard drive. The problem is with the browser because the Processor Explorer (available from Microsoft) shows Firefox as doing the constant disk activity, and hard drive stops making noise when the browser is closed.

I have Firefox Version 94.0.2 (64 Bit) running on Windows 11. First, I noticed Firefox was running very slow. It loads up slow and webpages are loading super slow. I downloaded other Browsers and they are working just fine so this tells me there is an issue with Firefox. After a while, Firefox would randomly crash for no apparent reason, while loading a new webpage or installing an Extension. I have sent Feedback for every crash. I have closed all of the Tabs I can that I am not using on Firefox, cleared the Cache, Cookies & History, Restarted Firefox & my PC and everything I can think of. Now, I just started getting an Error Message at the top of Firefox that says this: Firefox is running out of disk space. Website contents may not display properly & it includes a link to read on how to optimize disk usage. I followed the Instructions in that Article and it did not help. I am at wits end. I am ready to Uninstall and Reinstall Firefox and see if that fixes the issue but I hate to lose all of my Extensions and ETC. Can someone please help me with this? Is there anything else I can do to speed Firefox up, stop the crashes and get rid of that error message?
